An access terminal may switch to a different mode of wireless network selection as a result of manual selection of a wireless cell set (e.g., a closed subscriber group) associated with one or more wireless cells. For example, if the user of an access terminal selects a closed subscriber group in a wireless network that is different than the current wireless network, the access terminal may enter a manual mode of wireless network selection, select the wireless network corresponding to the closed subscriber group, and register on a closed subscriber group cell in the selected wireless network. In addition, an access terminal may automatically switch to a different mode of wireless network selection (e.g., the prior mode) upon losing coverage of a wireless cell set. An access terminal may also automatically select a cell of a wireless cell set if the access terminal returns to a cell of the cell set within a defined period of time after losing coverage of the cell set. Furthermore, an access terminal may return to a prior wireless network upon losing coverage of a wireless cell set.

1. A method of communication, comprising: selecting a cell advertising a closed subscriber group, wherein selecting the cell comprises: scanning for available cells advertising at least one closed subscriber group;displaying a list comprising at least one identifier corresponding to the available cells advertising at least one closed subscriber group; andselecting one of the available cells based on an indication from a user input device;identifying a public land mobile network (PLMN) associated with the selected cell;switching from an automatic mode of PLMN selection to a manual mode of PLMN selection as a result of the identification of the PLMN; andregistering at the identified PLMN. 2. The method of claim 1, wherein the switching is performed as a result of a determination that the identified PLMN is different than a currently registered PLMN. 3. The method of claim 2, wherein: the identified PLMN comprises a visited PLMN; andthe currently registered network comprises a home PLMN. 4. The method of claim 1, wherein the switching is performed as a result of a determination that the identified PLMN is different than a currently preferred PLMN. 5. The method of claim 4, wherein: the identified PLMN comprises a visited PLMN; andthe currently preferred PLMN comprises a home PLMN. 6. The method of claim 1, wherein: the automatic mode of PLMN selection is defined to be used when camping on a macro cell; andthe manual mode of PLMN selection is defined to be used when camping on a closed subscriber group cell. 7. The method of claim 1, wherein the selection of the cell results in camping on the cell, the method further comprising: maintaining a record of the automatic mode of PLMN selection;determining that the camping on the cell or camping on another cell of the closed subscriber group has ceased; andreturning to the automatic mode of PLMN selection identified by the record based on the determination. 8. The method of claim 7, further comprising selecting the cell or another cell of the closed subscriber group for establishing communication if wireless coverage of the cell or the another cell is entered within a defined period of time after the determination the camping on the cell or the another cell of the closed subscriber group has ceased. 9. The method of claim 8, wherein the establishment of communication comprises accessing the cell or the another cell or camping on the cell or the another cell to receive at least one of the group consisting of: pages, data, and broadcast information. 10. An apparatus for communication, comprising: a cell selector configured to select a cell advertising a closed subscriber group, wherein selecting the cell comprises: scanning for available cells advertising at least one closed subscriber group;displaying a list comprising at least one identifier corresponding to the available cells advertising at least one closed subscriber group; andselecting one of the available cells based on an indication from a user input device;a network selector configured to identify a public land mobile network (PLMN) associated with the selected cell, and further configured to switch from an automatic mode of PLMN selection to a manual mode of PLMN selection as a result of the identification of the PLMN; anda communication controller configured to register at the identified PLMN. 11. The apparatus of claim 10, wherein the switching is performed as a result of a determination that the identified PLMN is different than a currently registered PLMN. 12. The apparatus of claim 11, wherein: the identified PLMN comprises a visited PLMN; andthe currently registered network comprises a home PLMN. 13. The apparatus of claim 10, wherein: the selection of the cell results in camping on the cell;the network selector is further configured to maintain a record of the automatic mode of PLMN selection;the communication controller is further configured to determine that the camping on the cell or camping on another cell of the closed subscriber group has ceased; andthe network selector is further configured to return to the automatic mode of PLMN selection identified by the record based on the determination. 14. An apparatus for communication, comprising: means for selecting a cell advertising a closed subscriber group, wherein the means for selecting the cell comprises: means for scanning for available cells advertising at least one closed subscriber group;means for displaying a list comprising at least one identifier corresponding to the available cells advertising at least one closed subscriber group; andmeans for selecting one of the available cells based on an indication from a user input device;means for identifying a public land mobile network (PLMN) associated with the selected cell;means for switching from an automatic mode of PLMN selection to a manual mode of PLMN selection as a result of the identification of the PLMN; andmeans for registering at the identified PLMN. 15. The apparatus of claim 14, wherein the switching is performed as a result of a determination that the identified PLMN is different than a currently registered PLMN. 16. The apparatus of claim 15, wherein: the identified PLMN comprises a visited PLMN; andthe currently registered network comprises a home PLMN. 17. The apparatus of claim 14, wherein: the selection of the cell results in camping on the cell;the apparatus further comprises means for maintaining a record of the automatic mode of PLMN selection;the apparatus further comprises means for determining that the camping on the cell or camping on another cell of the closed subscriber group has ceased; andthe means for switching is configured to return to the automatic mode of PLMN selection identified by the record based on the determination. 18. A computer-program product, comprising: a non-transitory computer-readable medium comprising code for causing a computer to: select a cell advertising a closed subscriber group, wherein selecting the cell comprises: scanning for available cells advertising at least one closed subscriber group;displaying a list comprising at least one identifier corresponding to the available cells advertising at least one closed subscriber group; andselecting one of the available cells based on an indication from a user input device;identify a public land mobile network (PLMN) associated with the selected cell;switch from an automatic mode of PLMN selection to a manual mode of PLMN selection as a result of the identification of the PLMN; andregister at the identified PLMN. 19. The computer-program product of claim 18, wherein the switching is performed as a result of a determination that the identified PLMN is different than a currently registered PLMN. 20. The computer-program product of claim 19, wherein: the identified PLMN comprises a visited PLMN; andthe currently registered network comprises a home PLMN. 21. The computer-program product of claim 18, wherein: the selection of the cell results in camping on the cell;the computer-readable medium further comprises code for causing the computer to maintain a record of the automatic mode of PLMN selection;the computer-readable medium further comprises code for causing the computer to determine that the camping on the cell or camping on another cell of the closed subscriber group has ceased; andthe computer-readable medium further comprises code for causing the computer to return to the automatic mode of PLMN selection identified by the record based on the determination. 22. The method of claim 1, wherein the switching from the automatic mode to the manual mode occurs in response to a user manually selecting the closed subscriber group.
